Hey i'm 28 years old, last week Tuesday i took my first Maderna covid vaccine shot, i had a small headache which i took an advil and it went away. The next day Wednesday night i had a small fever and felt my neck stiff and the back of my head uncomfortable. Thursday i woke up feeling lightheaded, like foggy and loss of concentration. at night when i would go to sleep i feel this heart beat sensation in my head and when i wake up i feel my body shaking internally, as in my body is not actually moving but i still feel that shaking sensation. This sensation would always happen when i try to fall asleep, which makes me wake up often in the middle of the night. Then last Wednesday soo almost a week later i had to go to the ER because the heartbeat sensation in my head was too much that i couldn't sleep at all. Didn't feel any pain though. I got an MRI in my head and everything was fine. Blood pressure was also fine. Got ibuprofen and took at night. The heartbeat sensation was not noticeable but my body shaking was still there. I woke up feeling my body shake but not physically. It last a couple of minutes after waking up. This is getting me depressed and anxious.
